Question

A person helped me change my browser from Internet Explorer 7 to FireFox. Now I cannot find the email link on FireFox. I right click in the upper toolbar & hit customize. Their is no email. When I hit customize, the icons shrink & I can see more icons on the upper toolbar. When I cancel out of customize, I can only see 2 of the icons & I cannot bring up any others. Does Firefox not use email or does it have to be G mail, ect. ? My email is dolls@xxxxxxx.xxx.
